### Calling Sequence

  `wavwrite(y,wavfile)`
  `wavwrite(y,Fs,wavfile)`

### Parameters

- `y`: real vector or matrix with entries in [-1,1].
- `wavfile`: string (The .wav extension is appended if no extension is given)
- `Fs`: integer, frequency sampling in Hz.

### Description

Utility function to save `.wav` sound file. `wavwrite(y,wavfile)` writes a sound file specified by the string wavfile. The data should be arranged with one channel per column. Amplitude values outside the range [-1,+1] are ignored.

`wavwrite(y,Fs,wavfile)` specifies in `Fs` the sample rate of the data in Hertz.

### Examples

      A=matrix(1:6,2,3);
      wavwrite(A/6,TMPDIR+'/foo.wav');
      B=wavread(TMPDIR+'/foo.wav');
      maxi(abs(A- round(B*6)))
